Why it works: Oregano and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 3,449 recipes. Both carry estragole, which smells anise, licorice. The science ↓

Ingredients
Directions
Prepare
Sort and soak beans overnight, then drain and discard soaking water.
In a 4-quart pot, sauté onion in butter or margarine until tender but not browned.
Simmer
Add soaked beans, 4 cups water, bouillon cube, ham (cut into 4-6 chunks), bay leaves, thyme, oregano, salt, and red pepper.
Bring to a boil; reduce heat. Cover and simmer until beans are tender, 1 to 1½ hours.
Thicken and serve
Remove 1 cup of beans from stew, mash in a bowl with a potato masher or fork.
Add mashed beans back to stew; stir to thicken.
Remove ham and dice.
Remove bay leaves and red pepper, if used, and discard.
Add diced ham and green pepper to beans.
Cover and simmer for 15 minutes.
Serve beans over fluffy white rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Provide the main body of the soup; mashed portion releases starch that thickens the broth.
- Ham
- Adds savory, meaty flavor to the broth and chewy bites in the finished soup.
- Onions
- Soften in fat to build a sweet, aromatic base for the soup.
- Butter or margarine
- Fat that carries flavor and softens the onions without browning them.
- Green bell pepper
- Adds fresh, slightly bitter vegetable flavor and a tender-crisp bite.
The step that matters
Mashing and stirring in the beans to thicken. Mashing only one cup releases starch that thickens the broth. Mashing too much makes the soup pasty, while skipping it leaves the soup thin.
Swap the oregano
How well each one fits the dish's main ingredients (beans, onion, butter, beef, ham, pepper):
- Garlicfits better
- Parsleyfits better
- Thymefits better
- Oreganothe original
Fit is the average pairing score against beans, onion, butter, beef, ham, pepper. Candidates are from the same food group and used in at least 100 recipes.
